Mammals are characterized by being an amniote, and has mammary glands that produce milk (there are some exceptions. These exceptions includes monotremes that lay eggs and has no nipples, but still produce milk. Others, such as marsupials, completes developments in mother's pouch, and not in a uterus.)
The vertebrate mammals possess a backbone. This is one of the distinguishing factors between the vertebrate and the invertebrate.
They have hair, they are warm blooded, they feed their young with milk that their bodies make.
They are warm blooded, have fur, and nurse they children,
Mammals, a branch of vertebrates, possess hair and mammary glands. No other vertebrates do.
The most obvious way in which mammals differ from the other four classes of vertebrates is that mammals nurture their young on mothers' milk.
jaguars, belong to the class mammalia, i.e., they are mammals. All mammals are in turn necessarily vertebrates. This can be stated because jaguars, just like all other vertebrates, possess a vertebral column throughout life, which replaces the notochord which was present in their embryonic life.
they have special pouches that they/ carry their babies in. Mammals like these are called marsupials.
Elks are vertebrates. An invertebrate has no backbone like a snail.
they are warm blooded
Yes, bats are vertebrates. Vertebrates are animals that possess a backbone or a vertebral column. Bats belong to the class Mammalia, which includes all mammals. Mammals, including bats, have a well-developed vertebral column or backbone, along with other defining characteristics such as being warm-blooded, having hair or fur, and producing milk for their young. So, bats are indeed vertebrates.
Cheetahs use the flexibility of their spine to create a spring-like effect, thus allowing them to run very fast. They also possess it for the same reason as any other placental mammal; to support their frame and body.
Hair and milk.
Bird and mammals are the only two groups of vertebrates which are warm blooded. Amphibians, reptiles and fish, the other vertebrate groups, are all cold-blooded.
There are many such features, including: 1. Mammals nourish their young with milk. 2. Mammals are warm-blooded. 3. Mammals have fur. 4. Mammals have a four-chambered heart. 5. Mammals are amniotes. 6. Mammals breathe oxygen. 7. Mammals have three middle ear bones and a neocortex. 8. Mammals have internal reproduction. Some of these characteristics are unique to mammals; others are found in some other vertebrates but not in all other vertebrates.
Vertebrates are just that vertebrates, that ALL have a backbone, fish, mammals, amphibians, reptiles, birds, marsupials, primates, rodents... etc.
